2. The joint movement that increases the angle between the two bones.






3. One of the irregular bones of the spinal column.






4. The bones of the limbs (appendages)






5. A skull bone that is one of the internal bones of the face; forms part of the nasal septum.






6. A toe made up of two or three boens called phalanges.






7. A freely movable synovial joint.






8. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






9. A slightly movable cartilaginous joint - such as the pubic symphysis.






10. The junction between two bones; can be completely immovable (fibrous) - slightly movable (cartilaginous) or freely movable (synovial).






11. Long - faced. Example: Collie.






12. A spheroidal articular surface on the proximal end of a long bone; present on the proximal ends of the humerus - femur - and rib. Joined to the shaft of the bone by an area that is often narrowed and called the neck.






13. The first - most cranial sternebra.






14. The joint between the pelvis and the sacrum that joins the pelvic limb to the axial skeleton.






15. The vertical portion of the mandible located at its caudal end; site where jaw muscles attach to the mandible.






16. Viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates joint surfaces.






17. One of countless tiny channels through the matrix of bone that bring blood in from the periosteum to the haversian canals in the centers of the haversian systems. The haversian systems run lengthwise in long bones while these canals come in at right

18. Rib whose costal cartilage directly joins the sternum.






19. The smallest and most medial of the three pairs of bones that make up the pelvis; forms the cranial portion of the floor of the pelvis.






20. Also known as the spinal column; the collective name for the cervical - thoracic - lumbar - sacral - and coccygeal vertebrae.






21. The central canal that runs the length of a haversian system; contains blood vessels - lymph vessels - and nerves that supply and nourish the osteocytes.






22. Membrane bone formation; the type of bone formation that occurs only in certain skull bones when bone froms in the fibrous tissue membranes that cover the brain of the developing fetus.






23. A band of fibrous connective tissue that is present in and around many synovial joints; connect the bones of the joint to each other.






24. The most common type of bone marrow in adult animals; consists mainly of adipose tissue. Does not produce red blood cells - but it can revert to red bone marrow if the body needs greater than normal blood cell production.






25. The group of vertebrae located dorsal to the abdominal region.






26. Bony arches below and behind the eyes of common domestic animals; in dogs and cats they form the widest part of the skull. Made up of the rostral - facing zygomatic process of the temporal bone joined with the caudal - facing temporal process of the






27. A freely moveable joint; also known as a diarthrosis.






28. The distal sesamoid bone of the horse; located deep in the hoof behind the joint between the middle and distal phalanges.






29. Skull bones that are part of the internal bones of the face; make up the caudal portion of the hard palate.






30. One of the three ossicles in the middle ear; also called the anvil - this bone is the middle of the three ossicles.






31. The healing tissue between the ends of a fractured bone that is eventually replaced by true bone as the fracture heals.






32. The fibrous membrane that covers the outsides of bones except for their articular surfaces.






33. Tiny channels through the matrix of bone. Threadlike projections from osteocytes communicate with each other and with blood vessels through these structures.






34. The most proximal bony structure of the pelvic limb; also known as the os coxae. Attaches to the sacrum dorsally at the sacroiliac joints and forms the hip joints with the heads of the femurs.

39. The hormone secreted by the thyroid gland that prevents the level of caclium in the blood from getting too high.






40. The epiphyseal plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. Areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full size - thes
